8 Claims.

The invention relates to improvements in devices for scoring andbreaking tile, glass, and like vitreous material.

The principal "object or the invention is to provide adevice of thisnature whereby tile and the like may be accurately and properly scoredand then cut or broken with great precision.

Another object of the invention is to provide a relatively light-weightand compact device designed so as to be readily portable and one whichis simple to operate.

Still another object of the invention is to provide a scoring andcutting device which shall accommodate extremely large tiles as well assmall ones and which is, furthermore, suitable for cutting the tilediagonally and in various other fashions, as may be desired.

In carrying out the invention, there is provided on a suitable elongatedsupporting base a pivoted arm which carries a cutter slide movablelongitudinally thereon, the slide bearing a cutter or scoring elementwhereby materiallocated on the surface of the base may be scored. Thearm is limited in its movement toward the base by contact ofits free endwith a buffer removably secured in the base at the end opposite thepivoted end of the said arm. Gaugemeans are arrangedin and foradjustment transversely of the base to properly guide and hold a tile orthe like for the scoring operation. To break a tile, particularly of thethinner types, provision is made for a breaker element which is fixed tothe pivoted end of the arm for cooperation with an anvil mounted in thebase for adjustment vertically toward and away from said breaker toaccommodate the thickness of the tile to be broken, a tile beingintended to be located therebetween and pressure exerted on the tile bypressing down on the said arm.

Thenature of the invention, however, will best be understood whendescribed in connection with the accompanying drawing, in which:

Fig. 1 is a plan view of the novel scoring and breaking device, and Fig.2 is a side elevation thereof.

Fig. 3 is an elevation of the operating end of 4is an elevation of theopthe feet or lugs I2 through which the member may be rested upon orafiixed to a surface of a suitable support (not shown). At one end ofthe base there is provided an upstanding bifurcated bracket I3 to whichis pivoted, as by means of an adjustable bolt, one end of an arm Id. Theopposite end of this arm rests normally upon a butter l5 removablyattached to the opposite end of the base, as by being screwed therein.

Mounted on the said arm to slide along the same is a carriage or slidermember I6 having a downwardly extending bifurcated arm I6 carrying ascoring element or die such as the wheel Il. This may be removably heldtherein by screw I8, on the shank of which itrotates, so that when acutter becomes worn, it may readily be replaced. In order to preventtheslider l6 normally from slipping ofithe free end of the arm, there isscrewed into the latter a cap'member I9 which may be removed when it isdesired to disassemble the device or remove the carriage.

At its pivoted end, the arm I4 has fixed thereto a breaker element 20 ofany well-known design and having a longitudinal and shallow groove 20along its median line. The breaker is arranged for cooperation with ananvil or breaker button 2| in the nature of a headed screw which isscrewed into the surface III of the base and is adjustable verticallythereof toward and away from the breaker element 20 to accommodatedifierent thicknesses of tile. A set screw 22 directed from the sidewall ll of the base may be provided to fix the anvil member in itsadjusted position.

To'locate properly a tile 25 or the like for cutting, one or more gaugemeans are provided for adjustment transversely of the base. For example,the surface ID of the base may be provided near its bulier end with atransverse groove 26 and is adapted to receive a bar 21 of a straightedge, provision being made for fixing the location of the straight edgeas through a set screw 28 extending inwardly from the front oi the baseto engage the samel To, accommodate larger tile and to provide forcutting at various angles, a further gauging means may be provided asthe rod 30 fitting through the base transversely thereof andoscillatable therein so that its finger or right-angle extension 3| maybe elevated above the plane of the surface III" of the base, asindicated by the dotted line position, Fig. 2 of the drawing. When thedesired adjustment has been secured, this" may be fixed by means of aset screw 32 passing into a lateral boss 33 from the base.

Further locations, particularly with respect to accommodating odd shapesand sizes of tile, may be secured by providing a series of sockets 35and 36 in the supporting surface ID of the base l and into which pins 31may be fitted in the required position, such pins being readilyremovable from the socket when no longer required.

In operating the device, the same may be rested upon a suitable table orbench or, if necessary, secured thereto through the lugs "l2; Thereuponthe slider gauge or gauges are set for the desired cut and the tileplaced on the table and positioned against the gauge.

pivoted end of the arm and for scoring is drawn along the arm and overthe tile withthe scoring Wheel ll contacting the same to suitably scorethe tile surface. The tile may be placed between the breaker button orscrew 2| and the breaker 2|] with the scored line of break registeringwith the groove in the under surface of the breaker, the screw 2| beingadjusted so that the breaker is a slight distance above the surface ofthe tile. By'pressing'down on the arm, the tile will'break along theline of scoring. In the case of extremely large tiles, the breakage maybe efiected by cracking the tile with a hammer, in well-known manner.

Numerous advantages are found in the use of the novel device over thoseheretofore proposed. For example, its light weight and compactnesspermits it to be carried in the usualtile layers tool kit together withthe customary other tools.

The simplicity of the mechanical action makes possible ease of operationand'provides for accurate and rapid performancewithcle'an and neat cutrequiring no finishing operation.

Aside from the cutter, the'reis only one point where wear might occur,this being'w'here the arm I4 is pivoted to the upstandingbracket l3. Anywear, however, is readily accommodated by taking up on the adjustablebolt onwhich the arm rocks.

In view of the length of the arm"! which controls the breaking device,great power is afforded, and it "is possible to break tile of a heaviergauge than has ever before been cut.

The provision of the buffer in'additionto minimizing shock and noiseprevents the cutting element or wheel from touching any part of the tooland thereby preserving it from any damage from this source.

The tool, moreover, can be used by a mechanic ordinarily working inawkward positions such as in small shower stalls as it may be fastenedto the working board; and can be used, also, by either rightorleft-handed mechanics with equal ease simply by supplying a gauge withreversely directed stop.

A clear working base is obtained simply by inverting the bar whichremoves the gauge stop and leaves the base clear to insert tiles oflarge sizes or odd shapes.

When one or more cuts are to be made, the tile to be cut is held in thehand, placed against the gauge stop, scored, inserted in the breaker,and cut, the desired cut portion being retained in the hand.
